Answer:

she is going to make $408.90 in 18.2518.25 hours

Let's call the price before the VAT "x".

Then x plus that 20% VAT totals 14400.

The VAT is calculated as 20% of the original price, so 20% of x or 0.20x.

This gives us x + 0.20x = 14400.

Simplifying, we get 1.2x = 14400.

Dividing by 1.2 on both sides, we get x = 14400/1.2 = 12000.

Answer:

£18000

Step-by-step explanation:

\(x\) x 80/100=14400

80x=1440000

x=1440000/80

x=£18000

The parametric equation of the line drawn  ( 0. , 4.) and ( 4. , 0. ) is x + y - 4 = 0

A finite line segment is drawn from two points

Let the point be A and B

The co ordinates of the point A is (0, 4) and the co ordinates of the point B is (4, 0)

The equation of the line can be

y - y₁ =( (y₂-y₁)/(x₂ - x₁))(x - x₁)

y - 4 = ((4 - 0)/(0 - 4))(x - 0)

y - 4 = (4/-4)(x - 0)

y - 4 = -1(x - 0)

y - 4 = -x

y + x -4 = 0

Therefore, the parametric equation of the line drawn from  ( 0. , 4.) and ( 4. , 0. ) is x + y - 4 = 0

Answer:

\(-7^\circ C\)

Step-by-step explanation:

Let

x -----> the height in meters

y ----> the temperature in Celsius degree

we know that

The linear equation in slope intercept form is equal to

\(y+mx+b\)

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope or unit rate is equal to

\(m=-\dfrac{1}{100} \dfrac{^\circ C}{m}\) ---> is negative because is a decreasing function

The y-intercept or initial value is equal to

\(b=4^\circ C\) ----> value of y when the value of x is equal to zero (sea level)

substitute

\(y=-\dfrac{1}{100} x+4\)

For x=1,100 m

substitute in the linear equation and solve for y

\(y=-\dfrac{1}{100} (1,100)+4\)

\(x=-7^\circ C\)

The average value of a particular sample is known as sample mean

Sample mean is calculated by adding up all the values in the samples and after that dividing by the total no of observations in the sample

Options and definitions given in the question are not accurate

Because rather than sample means, we call it average of sample means

Sample means provides an estimate of the central tendency of the sample and it's basically a descriptive statistic

Suppose we have samples of five scores: 5, 6, 2, 8, 1

Then the sample mean would be :

\(\frac{(5 + 6 + 2 + 8 + 1}{5}\) = \(\frac{22}{5}\) = 4.4

Sample mean would be 4.4

The correct frequency distribution table for the number of car accidents is option A:

Number of accidents | Frequency
-------------------|-----------
0                  | 11
1                  | 10
2                  | 5
3                  | 3
4                  | 2
5                  | 1

To construct this table, we need to count the number of times each value appears in the data set. Hence, in order to construct a frequency distribution table for the number of car accidents list the possible number of accidents in ascending order and count the occurrences of each number in the given data.

For example, there were 11 people who reported being involved in 0 accidents, 10 people who reported being involved in 1 accident, and so on. These counts are then organized into a table with the corresponding number of accidents and their frequencies.

Hence, the frequency distribution table is option A:

Number of accidents | Frequency
-------------------|-----------
0                  | 11
1                  | 10
2                  | 5

Given :

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers  cost $0.05 each.

To Find :

How much would Mrs. Algebra's single order be.

Solution :

Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.

T = $(0.10 + 0.49 + 12.99 + 0.05)

T = $13.63

Therefore, Mrs. Algebra's single order cost is $13.63 .

Hence, this is the required solution.

The pair of numbers that would be in the columns, considering the proportional relationship, is given as follows:

20 would be in the column for 2, and 60 would be in the column for 6.

A proportional relationship is a special linear function, with intercept having a value of zero, in which the output variable is obtained with the multiplication of the input variable and the constant of proportionality k, as shown as follows:

y = kx

The table is extended to represent more equivalent ratios for 2:6, hence the constant of the relationship is given as follows:

k = 6/2 = 3.

Hence the equation is:

y = 3x.

The values given by each column are given as follows:

When x = 20, the numeric value of the relationship is of:

y = 3 x 20 = 60.

The order of events from least likely to most likely are as follows:

The reason for this order is because of the chances of each event occurring. Event D has the least chance of occurring because no numbers in the set have a value less than or equal to 0. Event A is the next least likely because only one number in the set is greater than 0, which is the number 1. Event C is the next least likely because only two numbers in the set are at least 2 (2 and 3). Event B is the next least likely, as there are only five even numbers in the set (2, 4, 6, 8, and 10). Events E, F, G, and H are the most likely to occur, because of the number of numbers that are divisible by 3, and 5, and are prime numbers.

Using the normal distribution, it is found that there is a 0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.

The z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The parameters are given as follows:

\(\mu = 42.05, \sigma = 0.025, n = 25, s = \frac{0.025}{\sqrt{25}} = 0.005\)

The probability that the mean weight of 25 pods of coffee is less than 42.035 grams is the p-value of Z when X = 42.035, hence:

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{42.035 - 42.05}{0.005}\)

Z = -3

Z = -3 has a p-value of 0.0013.

0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.

The probability that both randomly chosen people own a dog can be calculated using the concept of independent events. If 18% of people own dogs, it means that the probability of a person owning a dog is 0.18.

When picking the first person, there is a 0.18 probability that they own a dog. Now, assuming replacement (putting the person back before picking the second person), the probability that the second person also owns a dog is also 0.18.

To find the probability of both events occurring, we multiply the individual probabilities together: 0.18 * 0.18 = 0.0324.

Therefore, the probability that both randomly chosen people own a dog is 0.0324, which is equivalent to 3.24%. This means that if we were to repeat this random selection process many times, we would expect approximately 3.24% of the time to end up with two dog owners.

It's important to note that this calculation assumes independence between the events and replacement, meaning the probability of one person owning a dog does not affect the probability of the other person owning a dog.

To find the number of local minima of the function f(x, y) = x² + y² - 4ry + 39 on the set S = {(x, y) | z² + y² < 36}, we need to examine the critical points of the function within the set S and determine their nature.

To find the critical points of the function f(x, y), we need to calculate the partial derivatives with respect to x and y and set them equal to zero. Taking the partial derivatives, we have:

∂f/∂x = 2x

∂f/∂y = 2y - 4r

Setting these derivatives equal to zero, we find that the critical point occurs at (x, y) = (0, 2r). Next, we need to determine the nature of the critical point. To do this, we can evaluate the Hessian matrix of second partial derivatives:

H = | ∂²f/∂x² ∂²f/(∂x∂y) |

| ∂²f/(∂x∂y) ∂²f/∂y² |

Calculating the determinant of the Hessian matrix, we obtain:

det(H) = 4

Since the determinant is positive, this indicates that the critical point is a local minimum. Therefore, there is exactly one local minimum for the function f(x, y) = x² + y² - 4ry + 39 on the set S = {(x, y) | z² + y² < 36}. The correct answer is (b) 1.

Systematic risk is the type of risk for which you can be rewarded with a higher expected return.

So, the correct answer is A

Systematic risk, also known as market risk or non-diversifiable risk, affects the entire market and cannot be eliminated through diversification.

Investors are compensated for taking on systematic risk through higher expected returns as they bear the fluctuations and uncertainties associated with the overall market.

In contrast, firm-specific, diversifiable, and idiosyncratic risks are specific to individual companies or industries and can be mitigated through diversification in an investment portfolio, so investors don't get rewarded with higher expected returns for these types of risks

Hence, the answer of the question is A.
